java期末大作业完整代码，JAVA作业题求助求代码

生活百科经验分享

1，JAVA作业题求助求代码我将所有内容编写在一个文件中你可以将这些Bank中的私有类提取到单个的文件中，作为公共类使用，代码如下package help20110415;import java.util.ArrayList;import java.util.List;public class Bank/*** 存款* @param amount* 存款额*/ public void Deposit(Double amount) public Double getBalance()public void setBalance(Double balance)@Override public String toString()public SavingsAccount(Double balance)public OverdraftException()
2，Java程序设计大作业这种作业额话，只能给你思路了，基本考察的是java的基本IO操作，主要用到文件File和一些输入输出流//学生类public class studentsstring xiaoming;string xuehao;string xingming;string xingbie;string chusheng;int chengji;public int getchengji()return chengji; }//设置成绩 public void setchengji(int chengji)this.chengji = chengji; } public string getxingming()return xingming; } //设置姓名 public void setxingming(string xingming)this.xingming = xingming; }public string getxiaoming()return xiaoming; }public void setxiaoming(string xiaoming)this.xiaoming = xiaoming; }public string getxuehao()return xuehao; }public void setxuehao(string xuehao)this.xuehao = xuehao; }public string getxingbie()return xingbie; }public void setxingbie(string xingbie)this.xingbie = xingbie; }public string getchusheng()return chusheng; }public void setchusheng(string chusheng)this.chusheng = chusheng; }}//大学生类public class bigstudents extends studentsstring xi,zhuanye;public string getxi()return xi; } //设置系 public void setxi(string xi)this.xi = xi; }public string getzhuanye()return zhuanye; } //设置专业 public void setzhuanye(string zhuanye)this.zhuanye = zhuanye; }}小型“学生成绩管理系统你这个是不是语言,开发平台,数据库
3，JAVA大作业一句一句看，其实不难的import java.util.Random;import java.util.Scanner;public class Testpublic static Random r = new Random(); public static void printMenu()System.out.println("(1) play another round");System.out.println("(2) exit the game");System.out.print("Selection:"); } public static void main(String[] args) throws ExceptionString content = null;Scanner scan = new Scanner(System.in);//while (true)//true在这里使得程序一直循环printMenu();//调用方法，打印出三句话 ...content = scan.nextLine();//读取输入System.out.println();// 输入内容是2，则退出程序if (content.equals("2"))break;//break 跳出当前的循环，也就是跳出while循环 ， 程序往下执行，若没有可执行则结束程序if (content.equals("1"))System.out.print("Text to Match: ");int count = r.nextInt(50) + 1;//得到1~50随机数，即[1,50]char[] letters = new char[count]; //长度为count的char数组for (int i = 0; i < count; i++)//i < count等价i < letters.lengthletters[i] = (char) (r.nextInt(26) + 97);//给letters[i]赋值，字母a~zSystem.out.print(letters[i]);}System.out.print("\n");long startTime = System.currentTimeMillis();//得到开始时间int correctCount = 0;content = scan.nextLine();//得到输入的字符串for (int i = 0; i < count; i++)if (content.charAt(i) == letters[i])//输入的字符串的每个字母和letters中的比较correctCount++;}long endTime = System.currentTimeMillis();//得到结束时间int time = (int) ((endTime - startTime) / 1000);//计算所花的时间if (correctCount == 0)System.out.println("INCORRECTLY TYPED, YOU GET A SPEED OF 0!");elseSystem.out.println("共花了" + time + "秒,正确率为："+ ((int) (((double) correctCount / count)) * 100)+ "%");}}System.out.println();} }}给你实现第一句的吧 import java.util.scanner; /** * 随机数 。产生随机数的方法 ：math.random()*(end-start+1)+start * @version 1.0 * @author 点子二木 * @date 2008-12-8 * @right copyright (c), 点子二木 */ public class randomtest public static void main(string[] args) scanner input = new scanner(system.in); system.out.print("请设置随机题目的个数："); int num = input.nextint(); int start = -100; int end = 1000; for(int index =0; index&lt;num; index++)int first = randomint(start,end); int second = randomint(start,end); system.out.println("第" +(index+1)+ "题"+first+randomopration()+second+"="); } } /** * 产生int型随机数 * * @param start起始范围 * @param end截止范围 * @return */ public static int randomint(int start, int end) int result = (int) (math.random() * (end - start + 1) + start); return result; } /** * 产生随机操作符 * @return */ public static string randomopration() string result = ""; int random = (int) (math.random() *(100 - 0 + 1) + 100); int mod = random%11; switch(mod)case 1: result = "+"; break; case 2: result = "-"; break; case 3: result = "*"; break; case 4: result = "/"; break; case 5: result = "开方"; break; case 6: result = "e"; break; case 7: result = "幂"; break; case 8: result = "%"; break; case 9: result = "mod"; break; case 0:result = "比较";break;default: result = "+"; break; } return result; } }【java期末大作业完整代码，JAVA作业题求助求代码】
4，JAVA作业大家帮下public class circleprotected double radius; public circle()radius = 0; } public circle(double radius)this.radius = radius; } public double getArea()return Math.PI*Math.pow(radius, 2);} public void setRadius(double radius)this.radius = radius; } public double getRadius()return this.radius; }}public class cylinder extends circle protected double height; public cylinder()super();height = 0; } public cylinder(double radius,double height)super(radius);this.height = height;

} } }参考一下这个吧: 创建一个圆类Circle，该类可以接收圆半径，并具有计算圆周长和面积的方法 。import java.math.*;import javax.swing.*;class Circleint r;Circle(int r)this.r=r;}public void getS()System.out.println("面积是:"+Math.PI*r*r);}public void getL()System.out.println("周长是:"+2*Math.PI*r);}public static void main(String[] args)String s=JOptionPane.showInputDialog("请输入半径:");System.out.println("半径是:"+s);Circle c=new Circle(Integer.parseInt(s));c.getS();c.getL();}}class cylinder extends circle{这里自己写吧}-----------------package demo;/** * 圆对象 * @author saiya * */public class Circle/*** 常量  ， 圆周率*/ public static final double PI = Math.PI;public Circle(double radius)if(radius<=0.0)throw new RuntimeException("圆的半径一定要大于 0 ");}this.radius = radius ;

}}--------------参考下上面的public class circlepublic final double p=3.141592654;private double r;publicdouble getArea()//计算面积return this.p*this.p*this.r;}circle(double r)this.r = r;}}public class cylinder extends circleprivate double high;
